What is the zero of the polynomial 3x?.

a) About 99.7​% of organs will be between 205 grams and 415 grams.

b) The percentage of organs weighing between 240 grams and 380 grams is of 95%.

c) The percentage of organs less than 240 grams or more than 380 grams is of 5%.

d) The percentage between 240 grams and 415 grams is of: 97.35%.

These approximate percentages are defined by the Empirical Rule, for a normally distributed variable:

The first three questions are quite straight forward, while for the fourth we consider the symmetry of the normal distribution, as follows:

Hence the total percentage is of:

0.95 x 50 + 0.997 x 50 = 97.35%.

Answer:

40%

Step-by-step explanation:

There are 5 options to roll: 1, 2, 3, 4, and 5.

This means you have a 1 out of 5 chance of rolling each number.

This question is asking for 1 AND 2, not just one number. So, we have a 2 out of 5 chance of rolling that, because 2 options are acceptable instead of just one number.

I'm not sure which form you are looking for, but 2 out of 5 is the same as saying 2/5. Most probability solutions are wanted as a percentage. To find that just solve 2/5, which is 0.4. Move the decimal to the right twice, and that is a 40% chance.

The subsequent three words in the list. 3 14, 32, 60, 98, ... is 276 . In this case, the order is 3, 14, 32, 60, 98, and 276.

The next three terms in the sequence are 79, 90, and 101.

a) To find a formula for the sequence, we can use a difference table.

First, let's write out the first few terms of the sequence:

3, 14, 32, 60, 98, ...

Next, we'll create a difference table:

n | Term | Difference

1 | 3 |

2 | 14 | 11

3 | 32 | 18

4 | 60 | 28

5 | 98 | 38

We see that the difference is increasing by 10 each time, so our formula can be written as:

Term = 11n + 3

To check the formula, we can plug in a few values of n and see if it matches the terms in the sequence:

n = 1, Term = 11(1) + 3 = 14

n = 2, Term = 11(2) + 3 = 32

n = 3, Term = 11(3) + 3 = 60

The formula matches the terms in the sequence, so it is correct.

b) To find the next three terms in the sequence, we can use our formula:

n = 6, Term = 11(6) + 3 = 79

n = 7, Term = 11(7) + 3 = 90

n = 8, Term = 11(8) + 3 = 101

So the next three terms in the sequence are 79, 90, and 101.

The axis of symmetry is the y-axis and the vertex for the function

f(x) = 3(x - 2)²+ 4 is (2,4).

Given f(x) = 3(x - 2)² + 4

The graph will be symmetrical to the y-axis and since a> 0, the parabola opens up.

The axis of symmetry is the line that divides a parabola into two symmetrical parts. The vertex is the point where the axis of symmetry intersects the parabola.

The axis of the symmetry is x=2

The vertex form of a parabola is y = a (x - h)²+ k

The vertex is given by (h,k) coordinates.

In order to find the vertex, we need to compare the given equation to the vertex form of the parabola.

The point (7, 10.5) is on the graph of both equations and satisfies the system of equations.

To find the solution to a system of equations, we need to find the values of x and y that satisfy both equations simultaneously.

The system of equations is:

y = 2x - 3.5

x - 2y = -14

We can begin by solving one of the equations for one of the variables, for example, we can solve the first equation for y:

y = 2x - 3.5

Next, we can substitute this expression for y into the second equation:

x - 2(2x - 3.5) = -14

This gives us:

x - 4x + 7 = -14

-3x = -21

x=7

Now we can substitute this value of x back into the first equation to find the corresponding value of y:

y = 2(7) - 3.5

y = 10.5

So the solution to the system of equations is x = 7, y = 10.5.

The formula for the sum rule is: P(A or B) = P(A) + P(B) - P(A and B)

The sum rule, also known as the addition rule of probability, states that the probability of any two events occurring together is the sum of the probability of each event occurring individually, minus the probability of them both occurring at the same time. The formula for the sum rule is:

P(A or B) = P(A) + P(B) - P(A and B)

where A and B are two events and P(A) and P(B) are the probabilities of each event occurring individually, and P(A and B) is the probability of both events occurring at the same time.

The sum rule is used when the two events are mutually exclusive, meaning that they cannot happen at the same time. In this case, P(A and B) = 0, so the formula becomes:

P(A or B) = P(A) + P(B)

answer - (A)

Answer:

32.9 cm^2

Step-by-step explanation:

In the absence of a diagram, lets use the one shown in the attached worksheet.  The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries.  The approach is to calculate areas for both the circle and the square.

Square = (11 cm)^2              =  121 cm^2

Circle = (3.14)*(14/2 cm)^2  =   153,9 cm^2

Subtract the square from the circle.  That removes all the circle area, except for the four sections outside the square.  The result is 32.9 cm^2

Where "a" is the number of adult tickets sold and "c" is the number of child tickets sold.

We also know that the theater sold a total of 464 tickets, so we can add the following equation:

a + c = 464

We can now use the first equation to solve for one of the variables, and then substitute it into the second equation:

11a + 3c = 3520

3c = 3520 - 11a

c = (3520 - 11a)/3

We know that:

a + c = 464

We can substitute the value of c into this equation:

a + (3520 - 11a)/3 = 464

a + (3520 - 11a) = 464*3

a + 3520 - 11a = 1392

The total cost of the fence will be £841. The solution is obtained using the concept of perimeter of triangle.

What is perimeter of triangle?

Any two-dimensional figure's perimeter is determined by the space surrounding it. By summing the lengths of the sides, we can determine the perimeter of any closed shape.

We are given a right-angled triangle with one angle 59° and the adjacent side as 145 meters.

We know that tan θ = Opposite side/Adjacent side

⇒ tan 59° = Opposite side/145

⇒ 1.66 = Opposite side/145

⇒ 241 meters(approx) = Opposite side

Now, using pythagoras theorem,

⇒Hypotenuse^2 = Base^2 + Perpendicular^2

⇒Hypotenuse^2 = 241^2 + 145^2

⇒Hypotenuse^2 = 58,081 + 21,025

⇒Hypotenuse^2 = 79,106

⇒Hypotenuse = 281 meters(approx)

Perimeter of triangle = Sum of three sides

⇒ Perimeter = 145 + 241 + 281

⇒ Perimeter = 667 meters

The fence costs £ 1.26 per meter

Total cost of fence = 1.26 * 667 = £840.42 = £841
